The norepinephrine transporter (NET) is a key regulator of noradrenergic neurotransmission and homeostasis, regulating the norepinephrine levels in the brain and peripheral tissues. hNET is a major target in neuropsychiatric disorders such as major depressive disorder, autonomic dysfunction, and attention deficit hyperactivity disorder (ADHD). The human norepinephrine transporter gene (hNET, SLC6A2) contains 504 missense single nucleotide polymorphisms (SNPs). These SNPs have been identified in…
